What are the main diseases that are easily confused with colorectal cancer?

What are the main diseases that are easily confused with colorectal cancer? I believe many people have this question. Colorectal cancer has an insidious onset, often no obvious clinical manifestations in the early stages, and the disease progresses slowly. There are also many diseases that are easily confused with colorectal cancer. Let us learn about the diseases that are confused with colorectal cancer .

1. Idiopathic ulcerative colitis is one of the diseases that is confused with colorectal cancer. Colon cancer, especially papillary or cauliflower cancer of the left colon, often presents with symptoms such as diarrhea, mucus in stool, bloody stool, increased frequency of bowel movements, abdominal distension, abdominal pain, weight loss, anemia, etc., accompanied by symptoms of poisoning such as fever, which are similar to idiopathic ulcerative colitis. X-ray barium meal angiography is sometimes difficult to distinguish, with a misdiagnosis rate of up to 15%, and colonoscopy is often required for diagnosis.

2. Appendicitis. Ileocecal cancer is often diagnosed as appendicitis due to local pain and tenderness, especially in late-stage ileocecal cancer, where local necrosis, ulceration and infection often occur. Clinical manifestations include fever, increased white blood cell count, local tenderness or palpable masses. It is often misdiagnosed as appendicitis and treated conservatively. However, after a period of anti-inflammatory treatment, the mass does not shrink, or even increases, and then a tumor is considered.

3. Colon polyps Colon polyps are common benign tumors. Most of them occur in the sigmoid colon. The main symptom is blood in the stool, which is fresh blood and cannot be confused with feces. Some patients may also have purulent blood in the stool. X-ray examinations show filling defects. If fiber colonoscopy biopsy is not performed, polypoid colon cancer can be misdiagnosed as colon polyps. This is also a disease that can be confused with colorectal cancer.

4. Dysentery. Rectal cancer and sigmoid colon cancer often cause bloody stools and a feeling of tenesmus, so they are often misdiagnosed as dysentery. Therefore, for patients with long-term bloody stools, further examinations should be performed to exclude malignant tumors in the following situations: ① Seasons when non-infectious diseases are prevalent. ② There is more blood than pus in the stool. ③ Anti-inflammatory treatment is ineffective or relapses after effectiveness. ④ The patient is older. ⑤ Fecal occult blood is continuously positive. If necessary, even sigmoidoscopy should be performed.

The above is an introduction to diseases that are confused with colorectal cancer. Have you learned something about colorectal cancer through the above content? I hope that patients with colorectal cancer can actively seek treatment, maintain a good attitude, and recover soon!
